The sale of more than 760,000 shares of Facebook stock, valued at about $95 million, was made by Chan Zuckerberg Initiative Holdings and the Chan Zuckerberg Foundation, according to a regulatory filing Friday. The price of the shares ranged from $122.85 to $124.31.

It will be the first of many sales in Zuckerberg's plan to fund solutions for problems in health, science and education. After the birth of his daughter Maxima, Zuckerberg and his wife Priscilla Chan pledged to give away 99 percent of their wealth during their lifetime, reports Bloomberg.

At the time, the December pledge was worth about $45 billion. Since then, Facebook stock has gained more than 15 percent.
